Well, now you''ve isolated the problem. That''s a *huge* step!
I''ve seen
various recipes to configure Xen and iptables, but not seen a clean and
intelligible one: I''ve seen what is clearly a lot of gobbledy gook
written by script kiddies doing cut&paste. So I''ve used external
firewalls rather than spending the time to hand-brew my own.

That''ll have to change for me soon. I''d welcome good pointers
to good
write-ups to set it correctly.
